Outdoor Type (sun exposure)[

Basic StructureThe CR-LV consists of conductors and epoxy resin. Since the resin performs as insulation and housing which provides protec-

tion to the interior structure, additional bus ducts or housing are not necessary.

For outdoor installation (sun exposure), a sun shade is used to prevent the epoxy resin from being exposed to direct sunlight.

• Sunshade(steel)

While other bus ducts with metal housing require grounding, the CR-LV does not require additional grounding because the epoxy resin insulation

itself performs as housing. (Additional grounding is available on request. Please contact our design team for further information.)

Double-headed bolts are used to ensure a proper torque level when installing

the joint kit. If a torque wrench applies a pressure of 800 to 1000kgf·cm to the

outer bolt head, the head of the outer bolt and the tag attached to it will break

off on its own. Thus, it allows easy inspection for the proper application of the

bolts at the connection.

Double Head Bolts

Both joint plates of the joint kit and the conductors are tin plated. (A silver

plated option is available.) It prevents discoloration and corrosion of the joint

plates. In order to ensure easy maintenance and reliability, double -headed

bolts and visible labels are used to check the application, and a disc spring

allows an even connection of the contact surface.

Feature

The CR-Way uses a joint kit method.

Joint Kit

Precaution

Be sure to clean the interior of the connections prior to installation. Use caution not to twist the joint kit while inserting it, and after it is inserted.

An excessive pressure during installation may break the kit. Make sure that the double-headed bolts and the red tags are intact.

If a proper torque is not applied at the connection, it may cause heat during operation.

Hangers Both horizontal and vertical hangers are available for the CR-LV depending on the installation environment.

The standard horizontal installation method of the CR-LV requires two supports for each product. The standard 3 meter bus ducts are designed to be

installed at 1.5 meters intervals, and the space between the hangers should not surpass 2 meters at the most. (Please contact the design team for further

information.)

For vertical installation of The CR-LV, install the vertical hangers first, and fix the bus ducts on the hangers for better support.

The temperature rise limit is an important property which determines the performance of bus ducts. The temperature rise limit of the

bus duct is designed so that when a bus duct is operated with a rated current , the temperature limit values of the housing are within

55K as specified in IEC61439-2 and 6 [(previous standard) IEC 60439-1 and 2].

Ⅴ. Install Information

Before connecting the bus ducts, be sure to align them at the top and the bottom and the

left and the right as well as horizontally and vertically. (This applies for joint connection of

the horizontal and vertical ducts.) Make sure that the joint kit is not tilted. Be sure that the

surface is clear of particles before connecting them.

Check List

• The alignment of the bus ducts.

• The surface of the joint must be clear of dust or particles.

Using a torque wrench, slowly tighten the exposed bolt head of a double head bolt. Connect

the bus ducts temporally first, and check the function of the insulation (100MΩ or higher)

by checking the insulation resistance. Make sure the insulation is working normally before

breaking off the double-head bolt head. The double-head bolt head is designed to break off

at 800~1000Kgf•cm, therefore tighten the exposed head until it breaks off. Once the exposed

head and the red tag attached to it have been cut off, the state of the joint connection should

be visible, which means they are properly connected.

Check List

• Check the connection of the joint: The head of the double-head bolt and the red

tag should be cut off.

Assemble the ducts using a molding flask and rubber packing. Spray plenty of release

agent inside of the molding flask when the assembly is finished.

Check List

• Assembling the molding flask

• Spraying the release agent

• Assorting the vertical type and horizontal type

While assembling the molding flask, be sure to position the rubber packing of the mold-

ing flask at 40 mm from the block end. Make sure there are no gaps between the rubber

packing and the bus ducts.

Check List

• The location of the rubber packing: 40mm from the block end

Be sure to keep the ambient temperature at 25°C or higher before mixing the epoxy resin and

filler. When mixing the epoxy resin in a cool environment, be sure to cover the mixing container

to keep warm. It is to maintain the temperature of the container at 25°C or higher. In order of

filler, epoxy resin and hardener, add them into the mixing container, and mix it for 15 minutes

using a hand drill. (Please contact our design team for information about how to maintain the

temperature of the container when mixing the epoxy resin in a cool environment.)

Check List

• The ambient temperature: 25° C or higher

• Mix filler, epoxy resin and hardener for 15 minutes

Pour the mixture into the molding flask. Maintain the ambient temperature at 25° C. When

molding in a cool environment, cover the molding flask to keep warm to maintain the

temperature at the molding flask. Remove foams on the surface of the mixture for about

1 hour. Mold only three joints out of a total of four, and continue molding the entire line

following the same procedure. Wait for 8 hours, and check the function of the insulation

by checking the insulation resistance. When it is normal, finish molding the remaining

joint. (Please contact our design team for information about covering the container when

molding the epoxy resin in a cool environment.)

Check List

• Ambient temperature: 25°C or higher

• Removing foams on the surface of the mixture for 1 hour

Remove the mixture form the molding flask, and polish the rough surface with

sandpaper.

Check List

• When to remove the molding flask: 8 hours after the molding

• Polishing the surface with sandpaper

Perform the final inspection to check the performance of the joint.

• Final inspection of the joint
